The invention consists prima-rilyin a gas radiator embodying therein anouter hous-I ing, an element'within saidhousing the walls of which are laterally extended to form-a combustion .chamber towardthe bottom thereof, an expansion chamber toward the tops thereof, and a constricted passageway connecting said chambers, heat absorbing I members projecting from the inner walls of said tpassageway, radiating members projectrom the exterior walls of said passageta ke fiue, and a'gas burner within said com- 1 bustion chamber; and in such other novel features of construction and combination of parts as are'hereinafter set forth-and described, and more particularly pointed out in the c'laims hereto appended.

'In-the embodiment o'fthe-invention shown inthe drawings, I employ-an outerhousing open atthe bottom and having a. closed top. The frontwall of this housing, parlticularly the upperportion, is provided with open grill work'as at 11 to permit heatedair to flow from thehousing into a room. This housing preferably-is made of sheet metal and fwards the'top thereof as at 15,to' form an 7 expansion chamber 16 ,the capacity of which is relativelylower than that of-said combus tion chamber 14, the portion of the wall 17 between the laterally extended bottom and top portions forming a constricted passageway 18. Interforly of the walls 17 are vertically vextending inwardly projecting heat absorbing ribs or fins 19, positioned in the the top of the heat distributingelement also path of the rising heated gases in their pas sage from the combustion chamber 14 to the a expansion chamber 16. Said ribs or fins also act as bafiles to moreor less check a horizontal flow of such gases in their: passage from said combustion chamber 14 to said expansion chamber 16. 'These ribs or fins preferably possesseonsiderable bulk and are formed integrally withthe'walls 17 a of the constricted portion of the element.

- Exteriorly of the walls 17 of this constricted portion, and extending across the top of the combustion chamber'14 and the bottom of the expansion chamber 16, are radiating fins or ribs'2 0 which serve to conduct the heat from'the walls of the element and from the ribs or fins 19 and distribute it throughout the housing .10. Preferably the exterior ribs or fins 20Qa-re more numerous than the interior ribs orfins '19'1norder to secure a rapid conduction and radiation of the heat, both from-the fins 19 and from the material of the side walls of the element. 7

The expansion chamber16 is closed by a top plate 21. One end wall 22 closes the combustion chamber 14, the; expansion chamher and] the constricted passageway 18.

-The other end'wall 23, however, closes only the end of the combustion. chamber 1 the constricted passageway 18. 1 r

. and

Beyondtheend wall 23 and'above the lat erally extended portion 13, the element is provided with an extension 24, the upper portion of which conformsto and communie cateswiththe expansion chamber 16, and the lower portion ofwhich conforms to the constricted "passageway 18. The top of this extension is closed bythe top plate 21 and its end isvclosedrby a wall 25. The bottom of the extension is closed'by a wall 26 positioned above the combusion chamber 14:. Theendwall 25 is provided with a fine opening 27 positioned adjacent the bottom 26 of sa: d extension.

Exteriorly of the extension are heat radiating ribs or fins 28.

Ihe'back of'the housing 110 has an opening exten ing therethrough at 29 through which a flue pipey30jextends, this flue pipe being connected "wither box 31 which in turn communicates withfltheontlet opening 2710f the e tdist ibu ins l m Supported in any desired manner within tbs 'Qflmblfitifln chamber 14 is a gas, burner 32 of any desired construction,*this burner being positioned below "the passageway 18 so that the-flame from the burner openings will be directed within the constricted passageway 18.-

of noxious or injurious fumes, since all of the claim as new and desire to which is made removable, I secure economy of production.

The general construction of the radiator permits theus'e of an unfinished casting for the heating element without making the radiator at allunsightly, since this element is completely-concealed by the housing 10.,

.It is not my intention to limit the invention to'the precise number or arrangement'of the heat absorbing and heat radiating ribs,

or fins, it being desirable, however, to extend them about the tops of the wall formin the combustion :chamber and-the bottom o the wall forming the expansion chamber. p

The general'construction and arrangement of parts herein described has 'beenfound to products of combustion ar'e confin'ed within the heating'element which has no communi cationwith the'housing 10 through which the air used for heating purposes is circulated,

' It is not my intention to limit the invention to the details of construction shown in the accompanying drawings, it being vobvious that such may be varied withoutdepartin'g from the spirit and scope of the invention:
